forks are arranged with their broad) sides parallel to the direction ofthe length of the hook whereby the}; prevent the sheets from turning" onsaid forks.

Onwhat may he termed the hinged end of metal and flattened, and haswithin the same, the sliding bar or plate "7 in which are the slots 8 ofelongated quadrilateral form with their ends preferably rounded. In theupper and lower walls of the tube (3 are the slots 9 of elongated.quadrilateral form with their ends preferably rounded, said slotsl)registering with the slots 8, the latter being longer than, the Width ofthe impaling forks "-l, as mostplainly shown in Fig. l. e

Y To one end of theplate 7 is swi 'eleol the male screw 9, which isfitted thl female screw 10, the latter being firmly seclired in theinterior ofthe tube 6, whereby hyiiproperly rotating: said screw 9",inotionsl n. op-

' posite directions may be imparted to said plate 7. The outer end 11 ofsaid screw is accessible at the adjacent end of the tube 6, it beingsquared fortlie application of the key 12, whereby the screw may be conveniently rotated for the purpose intended.

It will be noticed thatthe impaling forks 4: are adapted to pass freelythrough the slots 8 and 9, .and that when the plate '2' is moved the endWalls of the slots are brought into contact with the adjaeentiiarrowedges of the forks, arid tightei'ied. there-- againsathus looking thehinge portions of the leaves 1 and 2, onelwith the other, and

preventing the disconnection of either leaf from the other, it beingseen that when the plate 7 is properly moved. it will he released of itsl'iolding action on the The L Then the leaf 21111) be removed, anrlsheets, etc, may be placed on, theleai": 2, and impaled by said forks,or sheets, etc., may be removed, it being evident that slots are formedin said sheets, etc., so that the latter may be fitted on said forks andwhen they arein position they are prevented from turning or twisting onsaid lorks owingto theflat sidesthereof. Then the leaf 2 is pressed downand the plate moved, whereby it is loolredtosaid forks, and thus saidleaf Qmay remain as a fixture on the sheets, etch,

The fixed plate 3, and the tube (3 are covered with piecesof canvas, bnckram or other fabric which in the present case constitutesportions of the hinges ot the leaves 1 and 2, to which. however, I donot limit myself;

Having thus described my invention what I claim as new and desire toSl'lfilll'Q by Letters Patent. l Z v A'loose sheet binder composed ofseparate leaves having hinge portions thereon, a stationar plateof rigidmaterial on the hinged portion 01" one leaf, a transversely extendingtube onthe hinge portion of the other leaf, a bar slidable in said tubeand having slots of elongated approximately quadrilateral form, saidtube having therein opposite registering slots of elongated form,impaling forks securedt'o said plate and entering said tube and bar inthe slots therein and flat and approximately quadrilateral in crosssection corresponding with said slots, and means for moving said'barendwise to impinge the end Walls of the slots of the tube against thenarrow edges of the forks and lock the hinge portions of said leaves onewith the other.
